Severe drought in the Po River and lakes threatens agricultural output and civil water supplies across Italy's Pianura Padana
Executive summary: The Po River and key lakes in northern Italy have dropped to one-third of their normal water levels, prompting emergency declarations in 101 municipalities across the Pianura Padana due to drought conditions affecting both agricultural and civil water use. The Pianura Padana produces about one-third of Italy’s agricultural output, including staple crops like rice and maize; prolonged drought threatens food supply chains, raises commodity prices, and increases public costs for emergency water logistics.
Who is involved: Italian agricultural producers (rice, maize, vegetable, and fruit farmers), civil water authorities, emergency management agencies, and consumers reliant on Pianura Padana water and food supplies.
Likely next: Continued monitoring of river levels, potential expansion of emergency zones, increased government funding for water transport and infrastructure, and possible EU-level agricultural aid requests if crop losses mount.
The Po River basin, Italy's most vital agricultural region, is confronting an unprecedented water shortage, with flow levels reduced to approximately one-third of historical averages. This acute drought, exacerbated by prolonged below-average rainfall and elevated temperatures, has triggered emergency responses across 101 municipalities in the Pianura Padana, where water scarcity now threatens both agricultural productivity and civil water supplies. Farmers growing rice, maize, vegetables, and fruit—crops highly dependent on consistent irrigation—are facing imminent yield losses, while local authorities have resorted to deploying 24 water trucks daily to supplement dwindling municipal supplies in the most affected areas. The crisis underscores a structural vulnerability in Italy’s water management infrastructure, particularly the lack of sufficient reservoir capacity to buffer against climate variability. Agricultural lobby group Coldiretti has reiterated its call for a coordinated network of artificial reservoirs (invasi) to capture and store water during wetter periods for use in dry seasons, a measure long advocated but inadequately funded. Without such investments, the region risks recurring seasonal emergencies that could undermine its role as a cornerstone of European food production. Near-term developments will likely hinge on the effectiveness of emergency water redistribution efforts and the pace of regional and national funding allocations for water storage projects. Meteorological forecasts indicating continued dry conditions through the spring and early summer suggest that pressure on water resources may intensify before any seasonal relief arrives, making adaptive water governance and infrastructure planning critical priorities for sustaining both agricultural output and public water security in the Po Valley.

Analysis — what this means
Likely next events
- If Po River levels do not recover by September 1, 2026, Lombardy and Emilia-Romagna regions may declare a state of natural disaster for agriculture.
- By August 25, 2026, regional water managers may impose mandatory restrictions on non-essential civil water use in affected provinces.
Sectors affected
- rice farming
- maize production
- vegetable and fruit agriculture
- bulk water transport logistics
Regulatory implications
- EU Solidarity Fund may be activated if crop losses exceed 5% of regional agricultural GDP, as per Regulation (EU) 2020/2094.
- Italian Civil Protection Department may extend emergency water truck authorization beyond August 2026 if drought persists.
- Ministry of Agricultural Policies may fast-track subsidies for drip irrigation and drought-resistant seed adoption in affected zones.
Historical parallels
- 2022 European drought caused ~30% drop in Po Basin maize yields and triggered emergency water rationing in 150+ municipalities.
- 2003 heatwave led to lowest Po River flows in 100 years, resulting in €2.3B in agricultural losses across northern Italy.
- 2007 drought prompted first-ever national emergency decree for water scarcity in the Pianura Padana, lasting 47 days.
